Our 20mm Blue Slate is a natural chipping derived from Welsh Slate quarries. Also known as Welsh Slate, whilst predominantly blue, the colour will vary between Blue, Grey and Plum depending on the veins being worked. 20mm Blue Slate is ideal for creating paths and patio areas as the flat 5-30mm chippings lock together creating a flat comfortable walking surface.
